It is a linear function because there is a constant rate of change in both the input and output values.
It is a nonlinear function because there is a constant rate of change in both the input and output values.
It is a linear function because the input values are decreasing.
It is a nonlinear function because the input values are increasing.
Which statement best explains whether y = 3x + 5 is a linear function or a nonlinear function?
It is a linear function because its graph contains the points (0, 0), (1, 0), (2, 8), which are on a straight line.
It is a linear function because its graph contains the points (0, 0), (1, 0), (2, 4), which are not on a straight line.
It is a nonlinear function because its graph contains the points (0, 5), (1, 8), (2, 11), which are on a straight line.
